Interdependency and Vulnerability of Multipartite Networks under Target Node Attacks

Figure 4

Network model for depicting the cascading failures on a two-layer network (networks A and B) with one-to-many correlations. The directed links are support links. The arrows point from the support nodes to the dependent nodes. (a) Nodes A1 and B6 are initially attacked. (b) Cascading failures on network A. Node A2 is removed because it is disconnected from network A. Node A7 is removed due to the lack of support. The removal of A7 further leads to the failure of node A6 as it is disconnected. (c) Cascading failures on network B. Nodes B1, B2, and B7 are removed as they have no supports. Node B3 is removed as it is disconnected from network B. (d) The LCC of the focal network in the final stable stage.
